BRICK-CUTTlNG MACHlNE.

SPECIFICATION forming part of Letters Patent No. 295,097, dated March 11, 1884.

i Application tiled December 28,1882. (No model.)

To LZ whom, it may concern:

Beit known that I, THOMAS MILES BAN- NIs'rnR, ot Lone Pine, in the county of Inyo and State of California, have invented anew and Improved Brick Cutting Machine, of which the following is a full, clear, and exact description.

The object of the invention is to improve scribed, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part of this specilication, in which si'miiar letters of reference indicate corresponding parts in all the gures.

Figure l is a longitudinal sectional elevation of my improved brick-cutting machine. Fig. 2 is a transverse sectional elevation. Fig. 3 is a portion of one of the reel-heads, showing the contrivance of the reel wire-supporting arms, and Fig. 4 is a detail of the guiding` or regulating contrivances of the cuttingwires, the same being in plan view.

The pressed clay is to be delivered from the pressing-machine, by any suitable means, in cakes on trucks c, which are to be caused to move successively along` ways Z1 under a reel, between whose heads c cutting-wires d are stretched at suitable distances apart, to out the said clay cakes transversely by the rotation ot' the reel as the car moves along, the said wires being guided or controlled by the vertical trai/cling guides e, soas to be made to enter and retire from the clay in vertical lines, to make square corners on the bricks, and the arms f, by which the said wires are supported, being capable of springing between the pins g and IL in the 'reel-heads, to allow such operation ofsaid wires. Vhen the clay is delivered from the pressing-machine onto the trucks, it is to be divided longitudinally to the required length of the bricks to be cut, as shown at j, Fig. 2. Thecutting-wires are then placed suitably distant from each other, to out the bricks edgewise, as shown at j', Fig. l;` but it is to be understood of course that the cakes may be delivered in suitable breadth for the width of the bricks to be cut at the Vends ot' the bricks by the wires, if desired. The reel-arms f are required to spring more, or,

rather, to have more freedom to spring when the cutting-wires enter the clay and perform their work than when withdrawing from the same. Consequently, I loca-te the pins h., over which the arms spring when the clay is being cut, near the inner ends of the arms, and place pins q nearer the outer ends, thus allowing the arms greater range in the one case than in the other. The said arms are arranged at each side between two disks forming each head of 6o k, besides being mounted on a shaft, Z, which is suitably mounted in bearings in the side frames or housings, m. The cutting-wires d. are stretched from the arms of the respective heads of the reel by means of adjusting thumbscrews n, to which they are connected so as to be tightened by theturning of the thumbsorews in the arms and twisting the wires, the said screws screwing forward and backward in the arms; but the wires may be connected to the screws so as not to be twisted by turning the screws. The guides e are carried on endless chains o, working on rollers p, suit-y ably arranged in the machine. In practice the reel may also be contrived to carry printing devices to impress the upper surface of the bricks q, and lightly print numbers or characters thereon.

The machine will connect at each end, respectively,with tracks from the press, and extending to the drying-yard, kiln, or other place, as desired, for simple and economical transference of the clay to the machine to be cut, and the cut bricks. therefrom to the place of delivery.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l1. In a brick-niaohine,the combination,with the rotary cutters d, of an endless belt, o, provided with guides e, arranged in pairs, with an opening between them, substantially as herein shown and described,whereby a square cut vwill be insured, as set forth.
